Universal KNX actuator with 8 freely configurable output channels for switch, shutter (AC/DC), fan coil, or valve control.
KNX Secure, configured via ETS5 or higher.
Switch outputs: time functions, 8 scenes, logic, status response, forced operation.
Heating actuator mode: switch outputs drive thermal heating valves directly (PWM or 2-point), without a separate controller.
Shutter AC/DC outputs: up/down, position 0-100%, louvre adjustment, 8 scenes, automatic sun protection, safety function, two modes (venetian blind / shutter).
Fan coil outputs: up to 3-level fan speed, step-switch and steering-switch modes, automatic, manual and forced operation.
Valve outputs: continuous (3-point), PWM and 2-point switching; valve-curve correction and automatic cleaning for continuous valves.
